You incorporate the principles of acrobatics into your every movement, displaying incredible flexibility and balance. You get the following benefits:

• Increase your Dexterity/Constitution to a max of 20.
• Your walking speed increases by 5ft. If you have a flying/climbing speed or gain one at any time after you take the feat, each also increases by 5ft.
• When you make a Dexterity save against an effect you see, you can use your reaction to make an Acrobatics check instead. On a success, you can move up to your speed to an empty space you can see. On a failure, you move half as far. You have a number of uses of this reaction equal to your proficiency bonus, regaining uses after a long rest.
